Answer:
c.0
Explanation:
Given, that apart from woman's paternal uncle and man's brother there are no more haemophilia cases and carriers in pedigree. This means that the woman's parents are not carrying the haemophilia allele and hence she will be non haemophiliac and non carrier. The man's parents are also not carrying the allele hence he will be non haemophiliac. Both man and woman are not carrying any allele for haemophilia so when they have children the probability of having haemophiliac children will be 0.
Hence, the probability of their first child having haemophilia will be 0.

Answer:
Electric current is the flow of electrons and they carry negative charge so electrons inside an atom repels the flow where as a proton attracts the flow.
Explanation:
- Electricity is the process of flow of electrons. During the flow these electrons share bonds or even transfer them.
- These electrons get energy when the potential difference is applied to a conductor that is moving in the direction from low to high therefore, the electrons move from one to another creating electricity.
- Though the electron repels the continuous flow but proton develops the force of attraction.
